when you feel like giving up..

What do you do when you just feel like giving up? Lately I've been feeling super down and out.. I feel like no matter what I do something always goes wrong.. I'll think I'm having a good day/good week etc and something will always bring it down and change things.. I've been having a hard time lately and idk what to do to lift my spirits..I've just been feeling like giving up on everything.. I just don't know what to do.. nothing seems to go right anymore even when I try my hardest.. what can I do to lift my spirits? I know there are ppl who probably have it worse than I do.. but I can't help but feel this way.. anything you do when you're feeling super down and hopeless??
